Header files not found on Mac OS 10.11

[jnsat]

When using a makefile such as

test:
    cxxtestgen --runner=ErrorPrinter -o slinkedlist-runner.cpp slinkedlist-test.cpp
    cxxtestgen --runner=ErrorPrinter -o dlinkedlist-runner.cpp dlinkedlist-test.cpp
    g++ -o test-runner slinkedlist-runner.cpp
    g++ -o test-runner dlinkedlist-runner.cpp
    ./test-runner

I receive the error

fatal error: 'cxxtest/TestListener.h' file not found

I think I had it installed via brew and it was working previously. It may have stopped when I upgraded. I tried downloading it from the site and added bin/cxxtest/bin to my path. I don't know where the header files need to be. I tried adding it do DYLD_LIBRARY_PATH but it seems by default that var is empty so it may not be the right one.

echo  $DYLD_LIBRARY_PATH
bin/cxxtest:

Solution:

xcode-select --install

See http://stackoverflow.com/questions/23905661/on-mac-g-fails-to-search-usr-local-include-and-usr-local-lib-by-default
Maybe it can be added to the manual. Which one is the right one?

Thanks, and sorry for getting to this so late! It's been a wild year for me so far, and I'm finally hitting my stride with projects that aren't work.
